Wi hwooao nr n ` METALLIC lanota-Tacna a full, clear, and exactdescription of the inf vent-ion, such as will enableothers skilled inthe art to which it appertains to make and use the' same, referencebeing had 'to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invent-ion relates to the construction lof metallic receptacles andparticularly to metallic shipping cases and has for its object tovprovide a knock-down metallic receptacle or case which can be quicklyand easily assembled for shipment and which can be quickly knocked downfor return shipment and storage.

A further object of my inventionis to provide a metallic shipping casewhich isparticularlyl simple in its construction, cheap and easy tomanufacture, strong, durable and efcient.

A further object of my invention is to provide a metallic receptacle orshipping case having its lock seams so constructed as to greatlystrengthen the structure in such manner that the seams will not becomebent or dented while the box is in transit.

ith these objects in view' my invention consists in the novelconstruction of the members of the receptacle or case which provides fora strong and rigid construction; and my invention particularly consistsin the novel construction of the lock seams as will be hereinafter fullydescribed and afterward specifically pointed out in the appended claims.i

Referring to the accompanying drawings:

Fig. 2 is a vertical sectional view takenon line 2 2 of Fig. 1. vertical sectional View taken on line 3-3 of Fig.1, and Fig. 4 is a horizontal sectional view through one corner of thebox as on line 4-4 of Fig. 1.

2, sides 3, ends 4 and bottom 5. As shown in Fig. 1 the -longitudinaledges of the ytop 2, bottom 5 and sides 3 are rolled in.suc h mannerthat they form a lock seam 6.

Referring to Fig. 4 it will be seen that the vertical edges of the sides3 and lends V4 are rolled in such manner that al lock seam is formed atthe juncture. y

Referring to Figs. 2 and 3 it will be seen that the transverse or endedges of the bottom 5 are bent upwardly to the point 7 The metal is thenbent back upon itself lto the point 8 where it is again bent back uponits-elf to the point 9. The metal is then bent back upon itself formingthe channel 10 and carried upwardly again to the' point 11 at whichpoint the metalis again bent back upon itself terminating at 12 adjacentthe bottom 5.

As will appear from Fig. 4 the vertical seams 6 are constructed bybending the vertical edges of the side 3 inwardly at substantially rightangles to the point 13 where-'the metal is bent back upon itself to thepoint 14, then bent back upon itself to the point 15, again back uponitself to the point 16 forming a channel 17, the metal being agairf bentback upon itself and terminating at 18. The channel 17 thus formedaccommodates the .turned edge 19 ofthe ends 4 whichturned edge is slidinto the said channel as is obvious. This construction of, lfolding themetal back upon itself greatly strengthens the seams and protectsthechannels 10 and 17 and the turned edges119 and bottomedge 2O of the ends4 againstdenting and mashing. In order to further cushion the seams andprotect the same I prefer to insert at the point 7 inthe transverse orend seams of the bottom 5 and at the point 13 of the lon-` gitudinal andvertical seams 6 a wire or stilfening member 13 running `the entirelength o-f each of the seams and having its ends bent backwardly overthe outside #of the metal as shown at 14. By this construc tion all ofthe seams are securely protected against denting and linashinef whiletheibox is in transit. I have found 7fiomiexperience that the usualconstruction of lockl seamsis insufficient to protect the edges'of` thecase or receptacle, itfrequently happening that they become mashed ordented to suchenextent that the case or receptacle can onlyf-be t-akenapart with `great "diliiculty frequently requiring-.the use' ofytools,for the` reason that should the lock seams become mashed Aordisligured the parts ofthe box become locked or jammed together. j

Referring now to Figs. 1, 2 and'` it will be seen that upon oneof theends 4 I provide a channel 14" at the upper'edge, said channel beingformed by bendin the edge outwardly to the pointv 21, then ack uponitself to the point122 anda ain back upon itself terminating at 23, saiychannel being designed to receive ,the top'2. The other end 4 vat itsupper edge is bent 'outwardly at substantially right angles to the point24 where it is bent under and back upon itself ter-v 4minating at 25adjacent the end 4. This construction provides ledgesor flanges at eachend of the box for convenient handling of the same, 'alth`ough desired Imay supply drophandles 26.011 the ends ofthe box as shown in Fig. 1. i

, The' top 2 when in position as shown in Figs. '.1, 2 and 3 may besecurely sealed by passed through means Aofa serles of wires 27 suitableperforations 28 in t e vendsof the box, the top 2 being provided withperforaj tions registerin v.with vthe erforations 21 in the ends of theox throug which the wires are' passed. l l Havingl thus fully `describedthe several parts of.- my invention its operation is as followsi''Ihelongitudinaledges of the bottom` 5 being formed' asbefore described andVthey side pieces Shaving their bottom edges turned as described th-said side are secured to the Vbottom 5 by sliding the lsaid turnededges into the channels 17 .on the bottom 5. Whenthe sides areinposition Athe end pieces 4, which asl shown inFig. 4,

are provided with vertical turned edges 19 and are forced down 'into thevertical chan* `ne1sf17fof the sidesA 3, the extreme bottom edge of eachend`4 enteringv the transverse channel 10 at each end of the bottom 5and as will appear from Figs. 2'and 3. When.

the bottom, sides and ends are thus in proper posltlen the case orreceptacle is ready to receive its contents, and after the samehave beeninserted the top 2 which has its longi.

tudinal edges formed,.as before described, identical with that shownin.Fig. 4 is slid mto position, the upper edges of the sides 3 beingturned to enter the channel 17 formed along the longitudinal edges ofthe top 2.

When the top is' in position shown in Fig. 1 the box may. be sealed bypassing the wires 27 through the'perforations 28 1n the' top and endsofthe box, and any lfurther or additional sealing means may bel suppliedin order to prevent rilin of the box and to.

insure delivery of the ori inal contents.

By the'construction of ox f ust described' all danger of' dentingfor masing the several seams iseliminate'd, for the reason that theI particilarconstruction lof the seams as 1 have described solstrengthens and`cushions the same that they can withstand any ordinary blow to whichthey might be subjected while-the box is in transit, as I have vfoundfrom experience thatla sharp heavy blow on the oiitside ofthe seams hasl no effect on' they channels and turned edges so that the interior ofthe seams is not daim aged inthe slightest degree.

Having thus fully described my invention j whatl claim'asnew and desirevto secure by Letters Patent of the United States is;

, l. Ina-metallic receptacle two members connected together at theiredgesbya .lock

seam, the edge of one of said'members being turned backupon itself, theedge of the other member being bent at an angle, then bent back u onitself to a point adjacent the surface of the last mentioned member atwhich point lthe metal is bent back upontself andagainbent back uponitself to form a chan'- nel to receive the said turned edge of the 'rstmentioned member, and a stiffening member interposedinthe edge of thellast mentionedv niexfiber on the outside of Isa'id channel.
